Our ice machine is making too much ice. When we open the door, ice spills out - so for some reason, whatever triggers the machine to know that it has enough ice made, seems to be malfunctioning. Any suggestions?

An ice build up around the top of the door aperture isn't unusual due to some cold dense air from inside will spill out when the door is opened to be replaced with humid lighter outside air that will tend to remain at the top for a while.

Being frost free doesn't exclude it from this type of ice build up as only ice formed over the evaporator during a cooling cycle will be melted by the defrost heater.

Persistent localised ice build up could be a sign of failing insulation but this will be marked by a cold spot on the outside of the cabinet.

Freezer fan error. Most likely the fan in your freezer has stopped working completely

Most refrigerators have a switch somewhere. look for a little white triangle either at the top or bottom. there may be a push button style somewhere along the upper hinge cover.

start with this site as it has your machines manual with trouble shooting section.

just to let you know you need to use nickel safe ice machine cleaner. and i hate to tell you this but if you are seeing silver chips in your ice your evaporator is shot. even if it is under warranty they will not give a new plate just for the reason of not using nickel safe cleaner. hope this helps you. i have seen this many times as im a service tech. alot of restaurant owners use coffee cleaner and also destroy their plates

Older icemakers have a bar that drops from above your ice bin; once the bin is full the bar is raised and trips turning the ice maker off so that it won't dump. If your's is this style, try manually pushing the free end of the bar upward so that it locks in the upward position. Newer ice makers with the ice bin in the door have a small panel that moves to the open position when the door opens and closes when the door closes. Mine also includes an optical sensor that is visible when this panel is in the closed position. Try placing a non-clear tape over the optical sensor (don't know if that will work or not but worth a shot). If effective in stopping the ice flow then call a repairman. If none of this works, turn off the water supply coming out of the wall to your freezer.

If you take the front cover off and look on the flip side of it, there should be a chart telling you exactly what the beeps mean. If it is not there or if you can't find it, let me know and I will clarify it for you. It may help to let me know how many times it beeps. It should beep from 1 to 7 times and then repeats. Also on the board, there is a very small reset button. Usually either black or white. You have to look very close, but it should be there. I would not reset it at this time, untill you find out what the beeps are trying to tell you. There is a reason the machine shut down on it's safety device. Good Luck and let me know if I can help

Make sure nothing is inhibiting air flow. I don't think it is advisable to store food in an ice machine however that is not likely the problem unless the food itself is inhibiting air flow. Most ice machine manufacturers recommend against storing any food in an ice machine. If there is a freezer component in you model the check to see if the evaporator coils are frosting up and the frost is blocking airflow causing the ice storage chamber to get warm. High humidity can cause frosting. Leaving a door to the ice maker open too long can cause frosting. A low refrigerant charge can do this although it seems logically like it should not. With a very slightly low charge one end of the evaporator gets super cold and the other end is not cold enough. Frosts starts collecting on the super cold end and accumulates across the evaporator coil to the other end eventually blocking all air flow. With too much humidity from open doors frost accumulates over the entire evaporator evenly but still blocks. You shut the unit down. It thaws out and works OK on restart until frost again builds up. If its not a frosting problem but it just stops making ice then the ice may not be releasing. Check the water supply and change any filters to insure good water flow. A good water supply is required for proper release and harvest of the ice in many ice machines. If the ice doesn't release it takes a shut down and thaw to clear the suspended ice out. Check for these things and write back if you need further assistance and can provide me with more details.

Hi sckk,
ngafm at your service,

Your indoor ice and water keeps getting iced up.
There is an air leak somewhere between the ice and water dispenser on the door and the freezer!
there are many places that this may be. But usually the spring loaded door where the ice drops out to the door ice machine!
It takes a good tech sometimes a couple visits changing a couple of parts till he gets it.
There is no sure fire way to diagnose which part is the culprit thats leaking air.You need an experienced tech that eyeballs it and knows what parts to choose first to be replaced.
The air leak almost microscopic to the eye.
Sometimes you take ice from the door and the crack only closes full some time after wards. Then the tech comes the next day and sees nothing. Or it is intermittent problem!

My advice is only a trained tech can remedy this problem, this time!
If I were there I'm sure I could nail it down!

You need hands on service!
Bless You ,
